Description

Technical Field

[0001] The present invention relates to the field of mold demoulding, and particularly to an automatic spraying device for demoulding agent. Background Art

[0002] With the rapid development of the national industrial level, the living standards of the people have been continuously improved, and people have put forward higher requirements for their living needs such as food, clothing, housing and transportation. As is well known, the development of transportation is a key factor in rapidly enhancing the local economic vitality, information communication and material transportation. Among them, high-speed rail transit has been regarded as the key development focus in recent years, such as high-speed railways spanning provinces, intercity commuter trains spanning cities, and light rails or subways commonly seen in cities. However, most high-speed rail transit requires operations to penetrate obstacles, such as subway tunnels and mountain tunnels. A large number of shield segments are required for this, so the production efficiency and quality of shield segments have become one of the extremely important links in the upstream industry.

[0003] At present, there are many problems in the production quality of shield segments, which are concentrated on whether the surface of the segments has a high cleanliness, because this involves the fitting between segments, the fitting between the segments themselves and the external environment, and the properties of the segments themselves. The demoulding of the segments from the mold has a great impact on the surface condition of the segments, so the type and coating method of the demoulding agent coated on the mold surface have become an important technology.

[0004] The demoulding agent is a functional substance between the mold and the finished product. The demoulding agent has chemical resistance and is not dissolved when contacting different chemical components. The demoulding agent also has heat resistance and stress resistance, and is not easily decomposed or worn; the demoulding agent adheres to the mold without transferring to the processed parts, and does not interfere with painting or other secondary processing operations.

[0005] At present, the spraying of release agents mostly relies on manual operation, that is, manually applying the release agent on the inner wall of the mold, or using a simple spraying device to spray the release agent on the inner wall of the mold. The manual spraying method not only wastes manpower and material resources, increases labor costs, but also has very low spraying efficiency, uneven spraying and low spraying quality, and there will be liquid accumulation, which affects the shaping of concrete materials. Although there are also release agent spraying devices on the market, such as a robot for spraying release agent on a track slab mold disclosed in the prior art 201820327090.9, and a track slab release agent spraying device disclosed in the prior art 201921684147.1, the prior arts all adopt a gantry truss structure, which is not only complex in structure, but also greatly occupies the factory building area; another example is the release agent spraying system and spraying method disclosed in 202010032601.6. Although the floor area is reduced, there are the following problems: 1. The rotary spraying mechanism is only provided with a horizontally placed spraying pipe, and it is impossible to spray the bottom surface, both end surfaces and both side surfaces of the mold at one time, and it needs to be sprayed step by step, resulting in low working efficiency; 2. The vertical moving mechanism is driven by an electro-hydraulic push rod. Since the shield segment is in an arc structure and the electro-hydraulic push rod has low precision, the spraying will be uneven; 3. The driving part of the horizontal moving mechanism is arranged under the base, resulting in the need to remove the base during maintenance or repair, which is time-consuming and laborious, and makes maintenance or repair very inconvenient; 4. The horizontal moving mechanism is driven by a lead screw. Under long-distance heavy load, the lead screw is easy to bend, resulting in uneven spraying. Summary of the Invention

[0012] Preferably, both of the guide rods are connected to the cross beam through self-lubricating bronze bushes.

[0026] Attached Figures 1-4The automatic spraying equipment for the release agent described in the present invention includes a horizontal moving mechanism 1, a support frame 2 vertically arranged at the driving end of the horizontal moving mechanism 1, a cross beam 3 horizontally placed with one end arranged at the top of the support frame 2, a lifting mechanism 4 arranged at the other end of the cross beam 3, and a spraying mechanism 5 arranged at the driving end of the lifting mechanism 4; the spraying mechanism 5 includes a support rod 51 horizontally placed and perpendicular to the moving direction of the horizontal moving mechanism 1, C-shaped brackets 52 respectively arranged at both ends of the support rod 51, a transverse spraying pipe 53 horizontally arranged below the support rod 51 and rotatably arranged at both ends on the C-shaped brackets 52 respectively, longitudinal spraying pipes 54 respectively vertically arranged and rotatable in the two C-shaped brackets 52, and angle adjusting components 55 respectively arranged on the two C-shaped brackets 52 for adjusting the inkjet angles of the transverse spraying pipe 53 and the longitudinal spraying pipes 54; during installation: the horizontal moving mechanism 1 is installed on the ground and placed parallel to the track 7 of the mold 6, and the spraying mechanism 5 is located directly above the mold 6; during operation: the mold 6 moves to the spraying station, then the horizontal moving mechanism 1 drives the spraying mechanism 5 to move above one end of the mold 6, then the angle adjusting component 55 adjusts the angle of the transverse spraying pipe 53 so that the nozzle of the transverse spraying pipe 53 is horizontally placed and faces the end face of the mold 6, then the horizontal moving mechanism 1, the lifting mechanism 4 and the spraying mechanism 5 work simultaneously, the lifting mechanism 4 drives the spraying mechanism 5 to move downward, and at the same time the horizontal moving mechanism 1 drives the spraying mechanism 5 to always maintain a set distance from the end face of the mold 6, and the spraying mechanism 5 sprays the end face of the mold 6 through the transverse spraying pipe 53; when the spraying mechanism 5 moves downward to the set distance, the angle adjusting component 55 adjusts the angle of the transverse spraying pipe 53 again so that the nozzle of the transverse spraying pipe 53 faces downward and faces the bottom surface of the mold 6, and at the same time the two longitudinal spraying pipes 54 face the two side surfaces of the mold 6, then the horizontal moving mechanism 1, the lifting mechanism 4 and the spraying mechanism 5 work simultaneously, the horizontal moving mechanism 1 drives the spraying mechanism 5 to move horizontally, and at the same time the lifting mechanism 4 drives the spraying mechanism 5 to always maintain a set distance from the bottom surface of the mold 6, and the spraying mechanism 5 sprays the bottom surface and the two side surfaces of the mold 6 through the transverse spraying pipe 53 and the two longitudinal spraying pipes 54 respectively; when the spraying mechanism 5 moves to the other end of the mold 6, the angle adjusting component 55 adjusts the angle of the transverse spraying pipe 53 again so that the nozzle of the transverse spraying pipe 53 is horizontally placed and faces the end face of the mold 6, then the horizontal moving mechanism 1, the lifting mechanism 4 and the spraying mechanism 5 work simultaneously, the lifting mechanism 4 drives the spraying mechanism 5 to move upward, and at the same time the horizontal moving mechanism 1 drives the spraying mechanism 5 to always maintain a set distance from the end face of the mold 6, and the spraying mechanism 5 sprays the end face of the mold 6 through the transverse spraying pipe 53, so that the bottom surface, the two end faces and the two side surfaces of the mold 6 can be sprayed at one time, which not only greatly improves the work efficiency, but also has uniform spraying and good effect; among them, the transverse spraying pipe 53 and the two longitudinal spraying pipes 54 are controlled separately. When the transverse spraying pipe 53 sprays the end face of the mold 6, the two longitudinal spraying pipes 54 do not work.

[0027] Further, each of the angle adjustment components 55 includes a first servo motor 551 disposed at the top of the C-shaped bracket 52 with its driving end extending into the C-shaped bracket 52, and a rotating shaft 552 connected to the driving end of the first servo motor 551 and located inside the longitudinal spraying pipe 54; a bevel gear transmission 553 for adjusting the inkjet angle of the transverse spraying pipe 53 and a synchronous belt transmission 554 for adjusting the inkjet angle of the longitudinal spraying pipe 54 are respectively disposed on the rotating shaft 552; during operation: the two first servo motors 551 respectively drive the two rotating shafts 552 to rotate, and the rotating shaft 552 can adjust the inkjet angle of the transverse spraying pipe 53 through the bevel gear transmission 553, and at the same time can adjust the inkjet angle of the longitudinal spraying pipe 54 through the synchronous belt transmission 554.

[0028] Further, distance sensors 56 are respectively disposed at the bottom and side of the two C-shaped brackets 52, which not only facilitate the precise control of the position of the spraying mechanism 5 by the horizontal moving mechanism 1 and the lifting mechanism 4, but also can play an obstacle avoidance role to prevent the spraying mechanism 5 from colliding with external objects, thereby providing a service life.

[0029] Further, both ends of the transverse spraying pipe 53 and the longitudinal spraying pipe 54 are connected to the C-shaped bracket 52 through bearings 57, and the bearings 57 are used to improve the service life.

[0030] Further, the lifting mechanism 4 includes a nut 41 rotatably disposed on the cross beam 3, a second servo motor 42 disposed on the cross beam 3 for driving the nut 41 to rotate, a lead screw 43 threadedly connected to the nut 41 and vertically passing through the cross beam 3, and guide rods 44 respectively disposed on both sides of the lead screw 43 and vertically passing through the cross beam 3; the upper ends of the lead screw 43 and the two guide rods 44 are connected through a connecting plate, and the lower ends are both connected to the support rod 51; during operation: the second servo motor 42 drives the nut 41 to rotate, and since the lead screw 43 is threadedly connected to the nut 41, the lead screw 43 makes a lifting motion, and by providing the two guide rods 44, the spraying mechanism 5 can be lifted more smoothly.

[0031] Further, both of the guide rods 44 are connected to the cross beam 3 through self-lubricating bronze bushes 45, and the self-lubricating bronze bushes 45 are used to improve the service life.

During operation: The third servo motor 15 drives the gear 16 to rotate. Since the gear 16 meshes with the rack 13, the sliding table 14 is driven to drive the spraying mechanism 5 to move horizontally.

[0033] Furthermore, the cross beam 3, the support rod 51, and the fixed frame 12 are all square tubes, which not only have a firm structure and light weight but also are standard parts, facilitating processing and manufacturing.

[0034] The above are only specific application examples of the present invention and do not constitute any limitation to the protection scope of the present invention. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the present invention's protection rights.
